The difference between them is 5, so multiply 250 by 5, then multiply 1250 by 5, and so until you reach the 11th term.
Let me know if this helps!😀

If p = 10 and q = 50 the terms are:
2 , 10 , 50 , 25
The n-th term of a geometric sequence:
xn = a rⁿ⁻¹
where a is the the first term and r is the common ratio.
in this case a = 2 , r = 5
x11 = a r¹¹⁻¹ = a r¹⁰ = 2 ∙ 5¹⁰ = 2 ∙ 9 765 625 = 19 531 250
